This is so true. You can have a hundred opinions from people saying this thing is just as good or better than the original. But when you buy their recommendation, you haven't bought the thing that you wanted!
Now, I don't idolise electric guitars. To me, there are a few characteristic sounds from the classic electric guitars, but are they so different? The amp, the pedals, the players... they have so much more of an effect, the brand is not even worth consideration. It's just cork-sniffing. Swapping pickups out for the exact same style of pickup? Just a waste of money. But if I wanted to buy a Les Paul (which I don't), would I be happy with a PRS, or an LTD? No, I wouldn't. If I want to buy a mic to record electric guitar, will I be happy if I don't get an SM57? No I won't. Tried, tested and approved, that's the bottom line.
